Application filed August 3, 1922.

. tively, of the borough of Brooklyincounty of the machine.

Kings, State of New York, borough of Manhattan, county of, New York,State of New York, and borough of Brooklyn, county of Kings, and Stateof New York, have jointly invented certain new and useful Improvementsin Adjustable Automatic Knitting Machines, of whichthe following is aspeci- .ficatioii.

This invention relates to improvements in adjustable automatic knittingmachines.

The object of the invention is the production of means to produceknitted material of predetermined lengths. Its second object is theproduction of a knitted material with stitches of various designs andcombinations and colors. The third object of the invention is theproduction of means whereby the various adjustments thereof can beeasily controlled by the operator. illie fourth object of the inventionis the production of a knitting machine whereby the speed of operationis greatly increased. A fifth object of theinvention is the productionof means whereby the yarns that go to .make up the finished product canbe changed automatically during the knitting operation to give certaincolors.

A sixth object of the invention is to automatically change the style ofstitches in the product produced during the operation of A seventhobject of the in: veiition is the production of a knitting machine inwhich the usual cam chains are not required.

The machine (see Figs. 1, 2, and 3') in this instance is indicated withthe table A, which is supported on one end on the double leg indicatedin its entirely by the letter B. The leg comprises the two vertical Lshaped members with the front flanges 40, which are connected by thecross members 41 and 43. Bosses 44 are formed with the leg B. Studs 46are supported 111 the bosses 44. A

frontcross brace 47 is supported on the outer ends of the studs 46, andhas formed therewith the central journal hub 48. A dial shaft 50 isjournaled in the hub 48 at its front portion and in one of the flanges40 at its rear end. An adjusting dial is indicated in its entirety bythe letter C.

The dial C (see Figs. 1, 2, 3, 6, 7, 28, 44

to 47) is indicated with the front wall 51 and the rim A circular dovetail groove 53 is formed in the front wall 51 and the circumferentialdove tail groove 54 is formed in the rim 52. An opening 55 extendsthrough the wall 51 and joins with the groove 53 and an opening 56extends through the rim 52 and joins with the groove 54. A groove collar58 is supported on the dial shaft 50 and bears on said dial C. A nut 59'in threaded engagement with the outer end of the shaft 50 secures saidcollar 58 and dial C in place. A spur gear 60 is fastened to the dialshaft 50.

A pair of journal bearings 85 extend from the bottomface of the table A and have journ aled therein the second cross shaft86. A spur gear 87 is fastened to one end of the second cross shaft 86and meshes with the spur gear 84. A spur gear 88 is fastened to theother end of the cross shaft 86. A second spur gear 89 is fastened tothe shaft 86 adjacent to the spur gear 88. An elongated bracket 93 isfastened to the leg B, and has formed in its opposite ends the journalhubs 94 and 95. A journal stud 96 is fastened to the hub 94, and hasjour naled thereon the spur pinion 97 that meshes with the spur gear 38.A sprocket chain wheel 98 is also journaled on the journal stud 96 andis fastened to the spur pinion' 9?. A second journal stud 102 isfastened to the hub and has journaled thereon the second sprocket chainwheel 103. sprocket chain 104 engages the sprocket chain wheels 93 and103. A journal lug 105 extends from the sprocket chain 104 and hasjournaled therein one end of connecting link 106 to lee-hereinafterdescribed.

On the second cross shaft 86 (see Figs. 1, 3, 42, 43, 45 and 47) isfastened a cam wheel designated in its entirety by the letter 1), andcomprises the hub 110, that has extending therefrom the flange 111. Apair of guide openings 112 and 113 are formed in the central flange 111,diametrically opposite each other. A guide wing 114 is fastened to theflange 111 which coacts with the guide opening 112' and a guide wing 115is fastened to the flange 111 and coacts' with the other guide opening113.

A third cross shaft (see 1, 2, 3 and 45) is journaled in journalbearings 121 extending from the upper face of the table A. A spur pinion122 is loosely supported on the shaft 120 and meshes with the spur gear89. A. locking earn 123 is fastened to the shaft 120. A pawl with thearms 124 and 125 is pivoted to the outer face of the pinion 122. The arm124 coacts with the cam 123 and a spring 26 bears between the arm 125and a lug 127 extending from the outer face of the pinion 122.

A boss (see Figs. 2, 3, 37 and 38) with a pivot 134 extends up from thetable A. A bell crank E with the arms 135 and 136 is pivoted to thepivot 134. A link 13'! has one end thereof pinned to the arm 136. A hellcrank is indicated with the arm 138 and the sector arm 139 with theteeth 140. The arm 138 is pinned to the link 13?. A link 141 is pinnedto the arin 138, by means of the pin 142. A cam rod is designated in itsentirety by the letter F. The cam rod F comprises the member 145 withears 146 at one end, and the care 147 at the other end, which latter areat right angles to the ears 146. A cam member 143 has one end pivoted tothe ears 147, by means of the pin 150. The said member 148 has formed onits upper edge the cam surface 151 and on itslower edge the cam surfaces152 and 154.
